Yup.

No, that's intentional. If you never run out of serial numbers,
it's not going to matter. If you do run out, you'll get an error
anyway (from trying to stuff a value > 2147483647 into an integer
column). And the sequence limit will be one less thing you'll
have to change on the way to fixing it.
